LAS VEGAS – In the not-so-distant future, couch potatoes will be waving, pointing, swiping and tapping to make their TVs react, kind of like what Tom Cruise did in the 2002 movie “Minority Report.” That’s the vision of TV manufacturers as they show off “smart TVs.”

The sets will recognize who’s watching and will try to guess what viewers want to see. They’ll respond to more natural speech and will connect with your smartphone in a single touch.

But don’t worry about “Big Brother” looking back at you. Manufacturers such as Samsung Electronics Co. will allow motion-capturing cameras to be pointed away.
